3. Importing Data Matlab Home Tab – Import Data Select the file to import
Click on the green check mark to import
‘whos’ to check the variable names & sizes

4. Match I-V Plots for Solution
Load Lines
A load line is used in graphical analysis of nonlinear electronic circuits, representing the constraint other parts of the circuit place on a non-linear device, like a diode or transistor.
It is usually drawn on a graph of the current vs the voltage in the nonlinear device, called the device's characteristic curve.
